Taken on a cell phone, the video "was so chaotic that it was hard to identify people, but the sounds of the screaming passengers made it perfectly clear that they were aware of what was about to happen to them," according to the French magazine Paris Match, which obtained the video along with the German newspaper Bild.

"One can hear cries of 'My God' in several languages. Metallic banging can also be heard more than three times, perhaps of the pilot trying to open the cockpit door with a heavy object. Towards the end, after a heavy shake, stronger than the others, the screaming intensifies. Then nothing," Paris Match reports.

The two publications described the video but did not post the video itself.

Lufthansa, meanwhile, announced that co-pilot Andreas Lubitz told told his Lufthansa flight training school in 2009 that he had a "previous episode of severe depression."

The airline is sharing that information and documents -- including training and medical records -- with public prosecutors.

Authorities have said Lubitz purposely crashed Flight 9525 into the French Alps on March 24, killing all 150 people aboard.

His girlfriend knew he had psychological issues but "did not know the extent of the problems," a European government official briefed on the investigation into last week's crash told CNN on Tuesday.

The girlfriend told investigators the couple were working through the issues together and "were optimistic" they could solve the problems; she was just as surprised as everyone else by what he did to the plane, the source says.

The girlfriend also told investigators Lubitz had seen an eye doctor and a neuropsychologist, both of whom deemed him unfit to work recently and concluded he had psychological issues, according to the source.

Lubitz complained about vision problems; the eye doctor diagnosed a psychosomatic disorder and gave him an "unfit for work" note, the source said.

Investigators are looking into whether Lubitz feared his medical condition would cause him to lose his pilot's license, the source said, adding that while flying was "a big part of his life," it's only one theory being considered.

Another source, a law enforcement official briefed on the investigation, told CNN earlier Tuesday that authorities believe the primary motive for Lubitz to bring down the plane was that he feared he would not be allowed to fly because of his medical problems.

Too stressed?

Lubitz told the neuropsychologist that he was too stressed with work, the European government official briefed on the investigation said.

The official said he was not aware of any suicidal tendencies reported by Lubitz to the doctors, but that investigators believe he was suicidal.

Airline officials have said that if Lubitz went to a doctor on his own, he would have been required to self-report if deemed unfit to fly.

The European government official also reiterated that German media tabloid reports that the girlfriend is pregnant or had major personal problems are all speculation and rumor.

The girlfriend and the co-pilot had not, as was widely reported by some media, broken up the day before the crash, the source said.

Official: Lubitz had suicidal tendencies

Earlier, a spokesman for the prosecutor's office in Dusseldorf, Germany, said Lubitz suffered from suicidal tendencies at some point before his aviation career.

Investigators have not found any writings or conversations where Lubitz shared his motives or confessed to any plans, prosecutor's spokesman Christoph Kumpa said.

However, medical records reveal that Lubitz was suicidal at one time and underwent psychotherapy. This was before he ever got his pilot's license, Kumpa said.

Kumpa emphasized there's no evidence suggesting Lubitz was suicidal or acting aggressively before the crash.

The prosecutor's office confirmed what some media outlets had reported about doctors deeming Lubitz unfit to fly, though there were no physical illnesses found.

Recovery efforts continue

While investigators search for clues to Lubitz's motivation, recovery workers continue the grim task of searching for the remains of those killed in the March 24 crash.

Lt. Col. Jean-Marc Menichini, Gendarmerie spokesman for the Provence-Alpes-Cotes d'Azur region, told CNN on Tuesday that a new path has been completed linking Le Vernet, a nearby community, to the mountainous ravine where the plane's debris is scattered.

It will be used by rescue teams to access the area, he said.

Capt. Yves Naffrechoux, also of the Gendarmerie unit, said Monday that the 1-kilometer path would cut down on the time it takes to reach the crash site considerably.

The trip will now take 30 minutes from Seyne-les-Alps, the staging post for the operation, with less walking involved and thus less fatigue, but also with fewer risks than helicopter transfers.

Two helicopters are still working in case weather conditions improve and allow them to fly, Menichini said.

The remains of at least 78 people on board the plane have been identified so far using DNA analysis.

Naffrechoux warned Monday that "it may not be possible to find the human remains of all the 150 passengers, as some of them may have been pulverized by the crash."

But French President Francois Hollande, speaking alongside German Chancellor Angela Merkel in Berlin, was more positive, saying that it should be possible to identify all the victims by the end of the week.

A simple stone memorial has been set up at Le Vernet, where grieving relatives of those killed have laid flowers and held prayers.

The opening of the road, which must still be paved, will eventually allow family members also to reach the spot where their loved ones died.

Authorities say there are some 26 families of six different nationalities in the area Tuesday.

However, Patricia Willaert, head of the Alpes de Haute-Provence district, told reporters that Lubitz's family was not among those to have come since the crash.

"There had been some rumors, but they have not come to the site," she said. "The family of the co-pilot has not come. We have no knowledge of information informing us of that."

Willaert said some 450 people close to the victims had already traveled to the area, with more expected to come during the Easter weekend.

"The priority has been to welcome them in the best possible way," she said. She praised the mobilization of local citizens, who spontaneously offered 2,000 beds to accommodate the victims' families.

German investigators and French criminal investigators are due to work together at the crash site Wednesday, Dusseldorf police said.

Medical record emerging

Much attention has focused on Lubitz's state of mind, with suggestions that he may have had mental health issues.

Lubitz, 27, passed his annual pilot recertification medical examination in summer 2014, a German aviation source told CNN. He had started working as a commercial pilot in 2013, said Lufthansa, the parent company of Germanwings.

An official with Lufthansa said that the exam only tests physical health, not psychological health.

It's unknown if Lubitz mentioned his problems on a form that asks yes-or-no questions about physical and mental illness, suicide attempts and medications. European pilots must fill out the form to be recertified.

Federal aviation authorities, not the airline, issue the form. The form is privileged information, and Lufthansa never sees a pilot's completed form, an airline representative said.

The airline would only get a "clear to fly" notice from the aviation doctors alerting the airline that a pilot has completed recertification.

Safety investigation

France's accident investigation agency, the BEA, said Tuesday that the ongoing safety investigation was focusing on a more detailed analysis of the flight history leading up to the crash, based on the audio recovered from the cockpit voice recorder and any other available data.

BEA spokeswoman Martine Del Bono told CNN: "A deliberate act by a man with a disturbed psychological profile is a possible scenario. The first step of the investigation is to describe more precisely what happened."

This will be based mainly on analysis of the cockpit voice recorder, to be supplemented by data from the flight data recorder if it is found, she said.

"But we will also look at other events with possibly similar scenarios, try to understand if there are systemic weaknesses which may contribute or facilitate such scenarios.

"We will in particular look at the cockpit door locking as well as the criteria and procedures applied to detect specific psychological profiles."

Lufthansa said in a statement Tuesday that it was canceling its 60th anniversary celebrations, planned for April 15.

Instead, the company will provide a live broadcast for its employees of an official state ceremony to be held April 17 in Cologne Cathedral for bereaved families and friends to remember the victims, it said.

Jurors first will be asked to determine whether Tsarnaev is guilty of 30 counts. Because 17 of those counts carry the death penalty as a possible punishment, a second phase of the trial will follow if the jury convicts him.

In the penalty phase, jurors would be asked to weigh aggravating factors, such as the heinousness of the crime, against mitigating factors, such as Tsarnaev's family history and his youth. He was 19 at the time of the bombings.

Red Cross focused on getting medical supplies into Yemen

The onslaught on Houthis rebels in Yemen continued Tuesday, with the Saudi-led coalition asserting increasing control while locals fled the chaos and casualties piled up -- dozens of civilians among them.

The U.S. Navy rescued two Saudi Arabian air force pilots from the Gulf of Aden, a U.S. military official said Friday. The pilots had ejected from their F-15 aircraft after experiencing mechanical failure, Saudi officials said.

Five days after their first airstrikes, the coalition has destroyed air defense systems of the Houthis and supporters of Yemen's longtime President Ali Abdullah Saleh, and rendered all but a fraction of air bases and stripes unusable, a Saudi source said.

Saudi Arabia's navy now controls all Yemeni ports, allowing only closely watched non-military medical goods to pass its blockade, according to the source.

This effort isn't over, including widespread attempts to locate and destroy Scud missiles still in the country, the source said.

The Saudis appear intent on seeing it through, as evidenced by remarks from Saudi Foreign Minister Saud al-Faisal in Riyadh.

"The Houthi militia and agents of the former president -- supported by Iran -- insist to meddle in Yemen, reshuffle the cards, rob the Yemeni will, make a coup against the constitutional legitimacy and reject all peaceful solutions," al-Faisal said, according to the state-run Saudi Press Agency.

"We are not warmongers," he added. "But if war's drums are beaten, we are ready for them."

The airstrikes -- the latest focused around Aden, Taiz and coastal cities -- come at a cost, and not just to Houthi rebel fighters.

The International Red Cross said that intense fighting had brought "disturbing reports of civilian casualties," with some of the worst violence around the port city of Aden.

Erich Ogoso, a spokesman with the United Nations' humanitarian agency, reported 182 dead and hundreds more wounded just between last Wednesday and Sunday. Some 75,000 people have been displaced in the past week, many health facilities shut down and food prices have skyrocketed.

"Increasing hostilities have led to (the) targeting of schools, health facilities and other social infrastructure," Ogoso said. "... There are reports of damage to residential areas in different cities, and in Aden, minors have reportedly taken part in the fighting on all sides."

Airstrikes that hit the Al-Mazraq camp for displaced persons near Sanaa killed at least 29 people -- women and children among them, according to aid group Doctors Without Borders. About 1,100 families live in the camp, said U.N.'s humanitarian affairs coordinator for Yemen, Johannes Van Der Klaauw.

"They are," he said, "among the most vulnerable people in Yemen."

Saudis, Iranians at odds

Yemen has been in disarray for some time, beset by widespread poverty and insecurity. Those factors helped terror groups like al Qaeda in the Arabian Peninsula find homes in the Arab nation, but didn't help its 26 million citizens in their quest for peace and prosperity.

The instability escalated as the Houthis, a minority group long marginalized in Yemen, increasingly challenged the government of President Abdu Rabu Mansour Hadi (who in 2012 took over for Saleh, who had been in power for 33 years).

The Houthis began moving into Sanaa in September, then headed into Aden earlier this month -- advancing despite intermittent (and, time and again, unsuccessful) talks aimed a peaceful political solution to the unrest.

Things finally came to a head last week, with Hadi -- who claims to still be President, even though the Houthis control government institutions -- left Yemen. At roughly the same time, Saudi Arabia and its allies came in with force to support Hadi, who they say remains Yemen's legitimate leader.

The burgeoning conflict threatened to open a wider rift, not just in the region but in the Muslim world. That's because the Saudis have painted the Houthis as tools of Iran's government, an accusation that also reflects the fact Saudi Arabia (and their allies in the coalition) are predominantly Sunni Muslims, while Iran and the Houthis are Shiites.

The state-run Saudi Press Agency quoted Saudi Minister of Foreign Affairs Prince Saud al-Faisal as saying Tuesday that he would not condemn Iran, but would instead test the country's intentions "by extending our hands to it as a Muslim neighbor to open a new page."

If those two countries could achieve real cooperation, it could ease the pressures that are tearing Yemen apart.

On the other side, Iranian Deputy Foreign Minister Hossein Amir-Abdollahian said that officials in his country and Saudi Arabia can help bring about a "political solution" in Yemen, according to Iran's state-run Press TV, citing AFP.

If they don't, war could inflame the entire region.

"We strongly object to the military solution in Yemen," Amir-Abdollahian said, reiterating a view made by other Iranian officials. "We believe that the Saudi military attack against Yemen is a strategic mistake."

The capital, Ankara, some 250 miles from Istanbul, also was affected. The outage extended to 45 of Turkey's 81 provinces.

The semiofficial Anadolu Agency quoted Energy Minister Taner Yildiz as saying the cause of the outage was unknown. Yildiz, speaking during a visit to Slovakia, said he could neither confirm nor deny that a cyberattack had triggered the blackout, the Anadolu Agency reported.

Flightradar24, which maps real-time flight data on the Internet, tweeted that the outage was "affecting flights," and said 11 of its 16 air traffic monitoring systems receivers -- as distinct from the country's air traffic control system -- were not working.

The Turkish Electricity Transmission Co. blamed the outage on a problem with transmission lines, Anadolu Agency reported. The utility said an investigation was in progress, as were efforts to restore power, the news agency said.

The outage began at 10:36 a.m. (3:36 a.m. ET). Nearly two hours later, according to Anadolu Agency, about 15% of the power had been restored to Istanbul and Ankara, including in some subway stations. Power also was beginning to flow again to a number of provinces that had been cut off, the agency reported.

By midafternoon, Yildiz said, 90% of Istanbul's power had been restored.

"Crowded places such as metro stations have been given electricity, and we believe the rest of the country should be fully powered shortly," he said.

Prosecutor taken hostage

Also Tuesday, a prosecutor in a controversial case was reportedly taken hostage by armed men at a courthouse in Istanbul.

Mehmet Selim Kiraz was assigned to the case of Berkin Elvan, a 15-year-old boy who was injured during the anti-government Gezi Park protests in June 2013.

The teen died the following March after having spent nine months in a coma. The case, with its overtones of possible police overreaction, has been politically contentious, just as the protests themselves were.

The prosecutor was taken hostage around 12:30 p.m. Turkish time in his office on the sixth floor of the Caglayan district courthouse, Anadolu Agency reported.

Police evacuated that floor of the building, the agency reported. Snipers were deployed, it said.

The agency said that two gunshots were heard as officers tried to get into the prosecutor's office, but it is not known whether anyone was hurt.

Negotiations between the gunmen and authorities were reported to have followed.

An explosion, followed by sounds of more gunshots, could be heard coming from the courthouse Tuesday evening, hours after the situation began. Smoke emanated from the building; the consequences of those sounds weren't immediately clear.
